Here we describe and illustrate and two new species of the Melastomateae tribe from Serra da Canastra National Park, Minas Gerais, Brazil. We also provide an updated identification key for the members of the tribe that occur in this Protected Area. has coriaceous leaves, broadly ovate to orbicular leaf blade, entire and adpressed-strigose margin, 11-17 basal acrodromous veins, and flowers with white petals. has the younger branches, both side of the leaf blade, bracteoles, hypanthium, and sepals, densely covered by viscous trichomes, as well as prominent secondary veins on the abaxial surface of the blade. Both species have stamens with a short pedoconnective and an inconspicuous ventral appendage. In addition to the descriptions of new species, we present comments, geographic distribution data, conservation status and images of plants in the field. We recommend that and should be included as of 'Least Concern' (LC) in the IUCN Red List.
在此，我们描述并阐释了来自巴西米纳斯吉拉斯州卡纳斯特拉山国家公园的野牡丹科两个新物种。我们还为该保护区内出现的该科成员提供了一份更新的鉴定检索表。[物种一]具革质叶，叶片宽卵形至圆形，边缘全缘且贴伏具糙伏毛，基部有11 - 17条离基三出脉，花具白色花瓣。[物种二]其较嫩的枝条、叶片两面、小苞片、花托和萼片均密被粘性毛，且叶片背面有明显的次生脉。这两个物种的雄蕊均具短花丝连接体和不明显的腹侧附属物。除了新物种的描述外，我们还给出了评论、地理分布数据、保护状况以及野外植物的图片。我们建议将[物种一]和[物种二]列入世界自然保护联盟红色名录的“无危”（LC）等级。
